Bad insulator

Blow-up mattresses make for really bad insulators - if you're sleeping on one in a cold environment, make sure to put a quilt or duvet underneath yourself as well as having bedding on top, otherwise all your body heat will leach out through the mattress and you will freeze your butt off all night.

(Not so much heard said, this one, but learnt through bitter experience.)
